Hints are welcome. However, running `debugperl -Dtls t/GdkWindow.t' provides lots of potentially useful information. I'm attaching a 203 kB compressed version of the output. In case it's too big to go on the list, I've also uploaded it there: http://gaffer.ptitcanardnoir.org/intrigeri/tmp/perl-Gtk2-free-invalid-pointer-debug.log.xz I've also uploaded the output with -Dtlsm there: http://gaffer.ptitcanardnoir.org/intrigeri/tmp/perl-Gtk2-free-invalid-pointer-debug-Dtlsm.log.xz If other perl -D options would help, please let me know. > Valgrind output would also be nice: > valgrind --tool=memcheck perl t/GdkWindow.t Here's the full output: valgrind --tool=memcheck perl t/GdkWindow.t ==4194== Memcheck, a memory error detector ==4194== Copyright (C) 2002-2013, and GNU GPL'd, by Julian Seward et al. ==4194== Using Valgrind-3.10.1 and LibVEX; rerun with -h for copyright info ==4194== Command: perl t/GdkWindow.t ==4194== 1..58 ok 1 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 2 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 3 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 4 ok 5 ok 6 ok 7 ok 8 ok 9 - An object of class 'Gtk2::Gdk::Geometry' isa 'Gtk2::Gdk::Geometry' ok 10 ok 11 ok 12 ok 13 - An object of class 'Gtk2::Gdk::Rectangle' isa 'Gtk2::Gdk::Rectangle' ok 14 ok 15 ok 16 ok 17 ok 18 ok 19 ok 20 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Drawable' ok 21 ok 22 ok 23 - get_geomerty ok 24 ok 25 - get_root_origin ok 26 - get_origin ok 27 - An object of class 'Gtk2::Gdk::Rectangle' isa 'Gtk2::Gdk::Rectangle' ok 28 ok 29 ok 30 - An object of class 'Gtk2::Gdk::ModifierType' isa 'Gtk2::Gdk::ModifierType' ok 31 ok 32 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 33 ok 34 ok 35 - An object of class 'Gtk2::Gdk::EventMask' isa 'Gtk2::Gdk::EventMask' ok 36 ok 37 - An object of class 'Gtk2::Gdk::WMDecoration' isa 'Gtk2::Gdk::WMDecoration' ok 38 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 39 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 40 ok 41 ok 42 ok 43 - An object of class 'Gtk2::Gdk::Cursor' isa 'Gtk2::Gdk::Cursor' ok 44 - An object of class 'Gtk2::Gdk::Pixmap' isa 'Gtk2::Gdk::Pixmap' ok 45 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 46 ok 47 ok 48 ok 49 ok 50 ok 51 ok 52 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 53 - An object of class 'Gtk2::Gdk::Window' isa 'Gtk2::Gdk::Window' ok 54 ok 55 ok 56 ok 57 ok 58 ==4194== ==4194== HEAP SUMMARY: ==4194== in use at exit: 7,259,240 bytes in 41,629 blocks ==4194== total heap usage: 97,372 allocs, 55,743 frees, 13,450,169 bytes allocated ==4194== ==4194== LEAK SUMMARY: ==4194== definitely lost: 42,210 bytes in 21 blocks ==4194== indirectly lost: 80,026 bytes in 34 blocks ==4194== possibly lost: 6,421,179 bytes in 33,491 blocks ==4194== still reachable: 665,913 bytes in 7,850 blocks ==4194== suppressed: 0 bytes in 0 blocks ==4194== Rerun with --leak-check=full to see details of leaked memory ==4194== ==4194== For counts of detected and suppressed errors, rerun with: -v ==4194== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0) ... interestingly, it seems that the "free(): invalid size" error doesn't happen under valgrind.
